In Brazil we have "É de cair o cu da bunda" "Makes the butthole fall out of the ass", which indicates something impressive/unexplainable.

And "Que que tem o cu com as calças?" "What does the ass have to do with the pants?". Which asks for the relation of two completely different things. It is generally used as doubting there's a relationship at all.

In Dutch "that hits (fits) like pliers on a pig", meaning that it's completely absurd.

"Blood crawl where it can't go", means that if you want it bad enough, you'll find a way.

"For an apple and an egg" means it's very cheap. But "little apple little egg" means it's very easy.

But my alltime favourite is "poepje", which is a term of endearment that little means "little shit"

It is not the yellow from the egg but I understand only train station. My lovely gentleman's singing club, I think I spider!

Spanish: me cago en la leche. I shit in the milk. Like... fuck, damn! Being annoyed at something.

Never fear the sea, fear the storm.

Dutch has a few that some say are insane-sounding but for me make a lot of sense as a native English speaker:

• Bekijk een gegeven paard niet in de bek "don't look a gift horse in the mouth"
• Ik geef een vinger en je neemt een vuist "I give an inch and you take a mile"
• De geest is uit de fles "the genie's out the bottle"
• De ene zijn dood is de andere zijn brood (literally "one's death is the other's bread" but I can't think of an English equivalent)
• Bier en wijn is fijn; wijn en bier is verkeerd "beer and wine is fine; wine and beer is queer" although that's quite a literal saying
• Een kruim is toch brood (literally "a crumb is still bread")

Croatian "Ovce i novce" - literally sheep and the money. Same meaning as have your cake and eat it. "Kašika mu u med pala" - spoon fell into honey, meaning he got lucky "Tako ti je grah pao" - this is the way beans fell, meaning it is what it is "Izvukao si deblji kraj" - you got the fatter end, opposite meaning from you got the shorter end. It's kind of a weird one, as it is also sometimes used to mean the same as the shorter end. "Da ti dupe puta vidi" - so your behind can see the trip. Meaning to travel for no special reason, usually used when a reason is given, but is probably just an excuse to travel

In Japanese they say "sonotori" translated literally it means "that bird" the English idiom equivalent is "on the nose"

"The bamboo is moaning" It's raining really hard.

I started listing some in Japanese, but realized this site does a better job than I could: https://www.fluentu.com/blog/japanese/japanese-idioms/ I've heard a fair number of those in person, some frequently.
